Cap reformation question

[J.C. Wren]

    I've got a system with a couple large electrolytics that hasn't been 
powered up in a number of years.  I have a 5A Variac.  What's the 
typical procedure for the reformation process?  Remove all cards (or 
maybe leave a junk card in for load?), start the Variac at 0V, increment 
by 10V every so often?  How long per step, and/or is a different step 
suggested?

    I've seen lots of people say "you'll need to reform the caps, 
first", but never a prodecure for it.
